RESILIENT WHEEL.

. Specification of Letters Patent. Patented Oct, 31, 1911; Applicationfiled February 21, 1911. Serial No. 609,882.

. tire does not come in contact with the ground and is thereby protectedagainst puncture. A further object of my invention is to simplify theconstruction of such wheels, so as to make them at the same time, cheapof manufacture and durable.

I attain the above-outlined objects by positioning the pneumatic tirebetween the rim and the hub, thereby protecting it from punctures.

With the above and other objects in view, as will more fully hereinafterappear, the present invention consists in certain novel details ofconstruction and arrangement of parts hereinafter fully described,illustrated in the accompanying drawings, and more particularly pointedout in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis speciin which similar characters of reference indicatecorresponding parts in all the figures, and in Which Figure 1 is a sideelevation of my improved wheel; Fig. 2 is an enlarged transversesectional View taken on the line 2-2 of Fig. 1; Fig. 3 is a detailedsectional View showing the spring means for connecting the hub; and Fig.4 is a transverse sectional view taken on the line 4-4 of Fig. 3.

In the drawings I have shown an outer metallic rim 1, carrying a solidrubber tire 2. Projecting radially inward from the inner periphery ofthe rim is a series of spacedapart projecting lugs 3, each of whichcarries a Y-yoke 4, the stem 5 of which is pivoted between theprojecting lugs 3 by means of a bolted connection 6. These yokes extenddiametrically toward the center of the wheel with each pair of lugsarranged in a plane transversely across the wheel.

The inner end of each of the legs of the yoke is reduced to form ashoulder 7, and the reduced portion 8 has projecting therefrom asubstantially rectangular spring member 9 having a closed end 10project; ing beyond the end of the reduced portion 8 and adapted to fita pocket 11 centrally disposed within each of a series of tubes 11]extending radially from the hub 12 and positioned on opposite sides of atransverse medial plane passing through the Wheel, as shown in Fig. 2.These springs 9 have a relatively broad flat bearing surface 13, whichis adapted to fit against a fiat-faced reinforcing strip 14 positionedon the longitudinally opposite sides of each of the pockets 11, as shownin Fig. 4. It will be seen that by this arrangement, there is afforded aspring connection between the hub and the rim which is reinforced to aconsiderable extent, thereby preventing relative torsion -between thehub and the rim, and which will be disposed with the travel of theWheel.

Centrally disposed and projecting inwardly from the crotch 15 of theyoke 4 and in a line with the stem 5, is an arched foot piece 16 curvedto fit the outside curved periphery of the pneumatic tire 17. Similarly,there is projected from the hub 13, intermediate the tubes 111, a seriesof outwardly-projecting pockets 18, carrying a Y- shaped foot member 19projecting therefrom and conforming substantially to the construction ofthe foot member 16 and positioned opposite to the same, adapted to fitabout and embrace the pneumatic tire 17.

It will be seen from this arrangement, that relative play may take placebetween the hub 12 and the outer rim 1 and its tire 2, due to the springconnection between the springs 9 and the pockets 11 on the hub12. At thesame time. any pressure upon the outside tire 2 is directly communicatedto the pneumatic tire 17 which will take up any shock or strain upon theouter tire, and the resiliency hf this inner pneumatic tire 17 willrestore the outer rim to its normal position with reference to the hub.

Many changes could be made in the above construction and many apparentlywidely different embodiments of this invention could be made withoutdeparting from the scope thereof. It is intended that all matterscontained herein, in the abovedescription, or shown in the accompanyingdrawings, shall be interpreted as illustrative and therebetween, andthat materials, sizes and relativities of parts are non-essential,except as called for in the claims.

; Having thus described my invention, I

- claim as new and desire to secure by Letters Copies of this patent maybe obtained for five cents each, by addressing the Commissioner ofPatents,

Patent:

1. In a resilient wheel, a hub, a series of pockets radially disposedabout said hub, a foot member disposed in each of said pockets, apneumatic tire carried by said foot members, and an outer rim encirclingsaid pneumatic tire, said rim being in spring engagement with said hub.

2. In a pneumatic Wheel,. "a hub, a series of pockets radially disposedabout said hub, said pockets arranged in pairs transversely of said hub,an outer rim, yoke members pivoted to said rim, means carried by thelegs of said yoke members placing said legs in frictional engagementwith said pockets, and resilient means interposed between said yoke andsaid hub, maintaining said members in their normal position.

3. In a resilient wheel having a hub, a series of pockets radiallydisposed about each end of said hub, a member having parts movable in apair of said pockets in transverse alinement, an outer rim pivoted tosaid member, a solld tire carried by said outer rim, a series of pocketsintermediate said first-named pockets, carrying members disposed in eachof said pockets, and a resilient rim carried by said members to absorbshock on said solid rim.

In testimony thereof I have signed my name to this specification in thepresence of two subscribing witnesses.
